@Rockhead,
No doubt you're pissed at the DNC for putting an end to their ads that feature Ann Romney's hobby/therapy of dressage.
Criticisim by the Right of Michelle Obama has been completely limited to her actions as First Lady.
I'm sure there is a wealth of good stuff Republicans could mine from her pre-White House days, but they haven't.
Since The First Lady represents our nation, and is on our dime, her excesses are fair game, as are the causes she goes public with advocating.
Criticizing Ann Romney for anything she says on behalf of her husband during this campaign, is fair game too.
No matter what her hobbies and indulgences cost, they haven't cost the American tax-payer a red nickel...unlike those of our current First Lady.
If you find her expensive hobby/therapy of dressage to be objectionable, good for you. Sounds like class envy, but then you're someone who agrees that the successful don't deserve their success.
If an when your tax-dollars go to feeding her horses, then your complaints will have substance, until then it's at best envy and at worse cynical mud slinging.
